It wont engadge so i just left it there for looks until i started running some higher boost and will need one for turbo safety.

Boost controller? and btw whats e10 fuel?

if its anything like here it dosent cost you at all to do the emmisions test hence why i said do the above and see how you go if you dont get past then have a look how far out you are and get a retune and go back agian but if you get through the first time bear in mind you can make a hell of a lot more emissions then cars around today ( early 90s falcoons and bommadores remember)
then you will save all the money for the retune and its cost you nothing.

dont put a stock cat on, you will have a heaps better chance with a new high flow item cats wear out after 80,000 100,000kms so putting one from the shead in my opinion is a waste of time and the guy here that works for them

his car just passed emissions making half that of the allowable emissions with
ported head
build bottom end
3540 turbo
haltech
280 cams
custom manifold and intake manifold
full 3" system and heaps of other bits and peices (350KW package)

with a brand new Catco 3" high flow cat

magna flow and catco are the best and are ADR approved

E10 fuel Ethanol blended fuel give you a bit of extra head room 10% of it is Ethanol so it burns to water and is better for emissions rather than posionous gases that the cat will have to convert

get a price on a magna flow item there because i can get them for a pretty good price here if they are pricey

just put a turbo smart boost tee on it as you can have one of those its only if you can mannaly change the boost levels from inside the car you can always say that your boost controller only runs 1 boost level

Nah i didnt mean get a crap used cat, i meant ill purchase a new magna flow.

So on the modifications report it says that i have to get engineers report and emissions tests...does this mean i have to do both or does this mean if i pass the test that its fine? or does the engineer do the test? I might go back to the pits, show them my letter, its called a "request to modify vehicle registation form" and then see what they tell me to do with it...go to engineer, go to emissions tests, both or either. I have internal boost controller with 3 presets but i only ever use one and i doubt they will figure out that my controller can use 6 Presets as it was confusing for me to figure out how to use the dam thing originally.

Soo list so far

Plumb back wastegate
Block bov or remove (mine doesnt engadge so thats fine)
Use e10 fuel
New Cat
drop the boost

Maybe i should scan the document i have so you guys can see what they have wrote...what you reckon?

**lookingforboost** · 24-02-2010 08:43 AM

what they want you to do is....

get an emissions report to prove its below its emissions for that year when you pass that you take the report to an engieneer and he will write up a report for you other modifications and give you a certificate that you keep with the car with that no more defects and no more stickers caz your car will be 100% legal on the road... or in theory anyway :P

**Limbo** · 24-02-2010 10:17 AM

i'm running a mangaflow steel cat with magnaflow muffler. The DB was only 81 when i tested it last.

haven't had to get the emmissions yet, piggyback system (not required in NSW) hondata qualifies as a piggyback.. yay!

Once engineered they can still defect you, just that its easy to get them cleared.

I've read through this very quickly as I have a passing interest in all things related to tests and laws regarding modified vehicles but I think the single issue here (or mistake if you don't mind me being a bit harsh) that is being overlooked is that an Engineer's certificate doesn't necessarily make anything modified on your car "legal".

So, you have a modded car and you have been issued with a 'yellow' or other infringement notice from your local authorities, or you are simply wanting to get some mods signed off?

An Engineer can do a noise test, he can check over safety aspects, check engine numbers etc, and he can do a brake safety check. All these facts he will write up in his report. You get an Emissions report from your local Emissions Test Centre.

You then take all this to your State licensing authority who will read the reports and THEN DECIDE if your car is allowed on the road. Just because the Engineer signs off doesn't give AUTOMATIC approval. Having said that, I think most authorities will be cool and give you registration, mod plate etc.

However, even being registered and having the Engineer's paperwork in your glovebox, doesn't exempt you from the forces of the law (I'm talking about the boys in blue here). If, in their opinion, your car is too loud/low/high/wide (tick whichever is applicable) they can hit you with an infringement notice.

So, as I said, the Engineer's certificate is not a guarantee. Neither is an Emission Report. You can fail an Emission's Test but it's up to the Engineer to decide if he will sign off on your emissions report. The RTA or whatever has to make the final decision. They can reject all the above if they want to (and I know some Engineering signatories charge big $$$ for their reports.)

Hope this clarifies some things.

And, yes, I do have some experience with this from earlier projects inc. a Supercharged Hilux conversion. One piece of advice I can give is to document everything you do to the car inc. photos, and put these in a folder when you present your car to the Engineer. Take it from me, he will love you for it, as it makes his job much easier (instead of having to ask you a thousand questions about this and that). Plus it shows you have nothing to hide.

In NSW its the RTA that runs the emissions testing so if you pass they cant knock you back.

but it is true my car is engeineered and i have been defected heaps of times i just take them to the pits and get the car passed agian though

What I was saying was that you don't necessarily have to PASS to get your engineer to certify your car's mods. If the RTA Emissions people look at your results and deem them CLOSE ENOUGH then they give you the paperwork and let your Engineer make the final decision. I think if you fail badly they don't give you any paperwork. The day I was there a guy with an imported RX7 was trying to pass (and he'd been there a few times already) but he didn't. He was running a JDM twin exhaust setup, but he'd had it modified, after failing previously, with two brand new cats and two mufflers on each pipe (total 4 mufflers) - he joked about not having any pipework just boxes connected to boxes. He got picked up in a random roadside Emissions test around Sans Souci (this was a few years back now.)

That's right!

That's what happened to me

Emissions Tech said its close to failing due to a cheap as x-force high flow cat and said I'lll leave ot up to your engineer..

My engineer said yup good enough for me

**040501912** · 25-02-2010 12:54 PM

oh crap.. u got to do emission ? i taught they were canceling it last year as the public wasnt notified and not many place in wa to do it??

at what rpm they do the testing?
tune the car to run lean at that rpm not so lean and give u detonations..

**Limbo** · 25-02-2010 04:13 PM

u need to tune to 14.7 AFR

I beleive all states are starting to follow suit.
Pretty sure EPA do it in NSW not RTA, & yes final decisionis up to engineer and then the RTA usually approve it on their recommendation, unless your engineer is known to be dodgey LOL

All types of RPM

They follow a driving game to simulate different things that should cover most conditions

They don't thrash the motor so 3/4 would more than likely been the max
